Abstract

ABSTRACT This study was aimed to analyze the growth performance of African catfish Clarias gariepinus cultured in the biofloc system at high stocking density. African catfish with an average weight of 1.85±0.09 g were cultured in four units of tarpaulin tank at a diameter of 1.72 m and a height of 1.05 m with a volume of ±2,000 L at the different density of 1,000 fish/m3; 1,500 fish/m3; 2,000 fish/m3; 2,500 fish/m3. During rearing period, fish were given the artificial feed with protein contents of 28.75% with the frequency of twice a day, as much as 3% of the body weight. The results showed that different treatment of high stocking density in the biofloc system had a significant effect on the absolute growth rate, lipid retention and energy retention (P<0.05) but not significant effect on daily growth rate. The results showed that the highest lipid retention and energy retention were found in the group of fish treated at a stocking density of 2,500 fish/m3 but declining protein retention and growth in fish occurred. The highest absolute growth rate and daily growth rate were shown by treatment with a stocking density of 1,500 fish/m3. Keywords: growth, stocking density, biofloc   ABSTRAK Penelitian ini bertujuan untuk menganalisis performa pertumbuhan ikan lele dumbo Clarias gariepinus yang dipelihara pada sistem bioflok dengan padat penebaran tinggi.  Ikan uji memiliki berat rata-rata 1,85±0,09 g yang dipelihara pada kolam terpolin berdiameter 1,72 m dan tinggi 1,05 m dengan volume air ±2.000 L sebanyak empat unit dengan kepadatan yang berbeda yaitu 1.000 ekor/m3, 1.500 ekor/m3, 2.000 ekor/m3, 2.500 ekor/m3. Selama 40 hari masa pemeliharaan, ikan diberi pakan buatan berkadar protein 28,75% dengan frekwensi dua kali sehari, sebanyak 3% dari berat tubuh. Hasil penelitian menunjukkan bahwa perlakuan perbedaan padat penebaran tinggi pada sistem bioflok memberikan pengaruh yang nyata terhadap pertumbuhan mutlak, retensi lemak dan retensi energi (P<0,05) namun tidak memberikan pengaruh nyata terhadap laju pertmbuhan harian. Hasil penelitian menunjukkan bahwa semakin tinggi padat penebaran terjadinya peningkatan retensi lemak dan retensi energi yaitu pada perlakuan padat penebaran 2.500 ekor/m3 tetapi terjadi penurunan nilai retensi protein dan pertumbuhan pada ikan. Nilai pertumbuhan mutlak tertinggi ditunjukkan oleh perlakuan dengan padat penebaran 1.500 ekor/m3.    Kata kunci: pertumbuhan, padat tebar, bioflok

Abstract

Waste management is a global problem in Indonesia. Salem Village is one of the villages in Brebes Regency where waste management is not optimal. The condition of the increasingly piled up waste without processing creates an unpleasant odor and disturbs the health of the surrounding community. The waste processing carried out is burning the existing waste, which adds to the problem of air pollution. As a result of continuous waste burning, the hangar was also burned. The impact of burning waste is very dangerous because it releases monoxide gas which disturbs public health. The purpose of this program is to provide socialization of waste processing, waste banks, Village Regulations on waste management, waste processing technology based on BSF flies and maggots into exoenzyme products that have economic value. Activity methods include lectures and discussions, training, demonstration plots and mentoring. Socialization to cadres and administrators of Bumdes Bina Usaha Salem Village regarding a) independent waste management and waste bank applications; b) socialization of village regulations (perdes) governing waste management, c) dissemination of information about organic waste processing technology based on BSF maggots and Ecoenzymes.The results of the socialization showed an increase in participants' knowledge about the necessity of business management and group management, village regulations governing waste management, the bioecology of BSF maggots, and the technology of organic waste bioconversion using BSF maggots. The training and demonstration plots provided to partners included preparation for waste processing, ecoenzym production, baby maggot maintenance, organic waste processing techniques with BSF maggots, and prepupa harvesting.  The evaluation of the activity showed that the pre-test scores initially ranged from 25 (5.88%) to 75 (5.88%). After the technology transfer, the post-test scores increased to a range of 60 (5.88%) to 85 (11.77%).  The Community Service Program can realize the independence of the residents of Salem village in managing organic waste.

Abstract

This study focuses on the growth and meat weight percentage of Hotate clams (Patinopecten yessoensis) during the rearing phase in Funka Bay, Hokkaido, Japan. Japan, as a major producer of seafood, including Hotate clams, plays a significant role in global seafood consumption. The objective of this study was to analyze the length-weight relationship of Hotate scallops and assess their meat weight percentage during the rearing phase. The research method involved observations using a random sampling technique during the period from August to October 2022. Samples were taken in Funka Bay, with coordinates between 42°20'-42°40' North and 140°00'-141°00' East at a depth of 43 meters. Results showed that the length-weight relationship of Hotate clams during August to October exhibited a negative allometric growth pattern, with the highest constant reaching 2.640. This means that length growth is faster than body weight. The percentage of Hotate clam (P. yessoensis) meat weight during the rearing phase ranged from 31.03% to 35.70%. This study provides important insights into the growth and meat composition of Hotate clams during critical phases in their culture in Funka Bay, Hokkaido, Japan. It can serve as a valuable information foundation for the management and maintenance of sustainable and productive Hotate clam aquaculture in the future.

Abstract

Hotate clams (Patinopecten yessoensis) are a species of Bivalvia that is often found in the waters of Funka Bay, Hokkaido, Japan. The information regarding the relationship between length and weight and condition factors for hotate clams is important for knowing their growth patterns. This research aimed to examine the length-weight relationship and conditions of 56 Hotate clams collected in August of 2022 at two different locations. The relationship between length-weight and growth patterns shows that the range of b values at stations A and B is 2.45, and 1.86 in the waters of Funka Bay while the growth pattern in Funka Bay displays negative allometric growth with r values ranging from 0.90-0.92 (strong positive correlation). The condition factor values for Hotate clams at stations A and B are 5.45 and 1.28. There is a good welfare value for Hotate clams because the condition factor (Kn) is greater than one.
